This year, the investigator undertook the project as follows.
<Study 1: A cross-sectional association of gaming disorder with internalizing and family factors in children and youths> The investigator finished analyzing collected data and posted the first draft of the manuscript as a preprint（Hamamura et al., 2024, PsyArXiv). Despite the significant association between child-reported gaming disorder and internalizing symptoms, β = .023, p = .03, the latent association measuring the cross-informant agreement was not significant, β = .004, p = .86. The only significant moderator was the parent-reported positive parenting behavior in the latent association between gaming disorder and internalizing symptoms, β = .004, p = .04. At the dyadic-level, gaming disorder and internet gaming disorder had the same pattern of associations with the other measures. In contrast, a different pattern emerged at the person-level. This multi-informant measurement may indicate a possible inflation of the self-reported positive association between gaming disorder and internalizing symptoms.
<Study 2: A longitudinal association between gaming disorder and internalizing in youths> The investigator completed the follow-up data collection.
<Study 3: A Japanese version of the Motivation for Online Gaming Questionnaire (MOGQ)> The investigator conducted a validation study for the translated scale and presented the findings at an international conference. The factor structure of the Japanese version of the MOGQ differed from that of the original scale.
